Rockhold, a former Strikeforce champion, is in discussion to face Lyoto Machida, possibly at UFC on FOX 13 in December. That card was announced, but no fights have been set for it so far.

“This fight is being discussed,” Cormier said. “Both guys are open to it. I’d like to propose they fight on UFC on FOX in Phoenix or the pay-per-view with (Chris) Weidman and (Vitor) Belfort.”

Rockhold (12-2) has made mention of being ready to fill-in for Belfort should the top contender not make it to December and his title fight with Weidman. Machida (21-5) lost to Weidman earlier this year, dropping to 13-5 inside the Octagon.

Since falling to Belfort in Brazil last year, Rockhold has downed both Costas Philippou and Tim Boetsch.
